Embodiment

[0031] As shown in the figure, the construction environment in this embodiment is relatively complicated, and the height difference between the aircraft stand platform and the approach road (need to borrow the road) is 22m. The effective use area of ​​the aircraft position is small, the effective use length is 40m, and the maximum effective use width is 30m. In such an environment, it is very difficult to install a 650t crawler crane.

[0032] In this embodiment, the boom of the 650-ton crawler crane is divided into two sections for assembly, one section is the main boom, and the other end is the tower boom. Among them, the 48-meter main boom and the 7-meter wind power pole head weigh 37 tons in total. According to the site conditions, two truck cranes are used for hoisting, and the weight of the 48-meter main boom + 7-meter wind power pole head is shared equally by the two truck cranes, that is, each truck crane bears 37 / 2=18.5 tons, and the hoisting weight is carried out ac...

Abstract

The invention discloses a method for mounting crawler cranes in side slope sites. The method includes steps of S1, preparing for construction, to be more specific, a, marking out appropriate lifting platforms for truck cranes, treating foundations and leveling the sites; b, selecting the appropriate truck cranes; c, transporting main units, crawlers, counterweights and main arms of the crawler cranes to main unit position platforms and assembling the main units, the crawlers, the counterweights and the main arms; d; respectively driving every two corresponding truck cranes to the corresponding lifting platforms and transporting tower arms onto the lifting platforms; e, respectively computing the stretching length required by each lifting arm of each truck crane, assembling the tower arms besides the lower-end lifting platforms and determining a lifting point for lifting each truck crane on the corresponding tower arm according to the position of the gravity center of each section of each lifting arm in the corresponding tower arm; S2, simultaneously lifting each tower arm by the aid of the two corresponding truck cranes; S3, grouping each tower arm and the corresponding main arm in the air by the aid of the two corresponding truck cranes; S4, operating the lifting arms of the truck cranes and taking off lifting hooks. The method for mounting the crawler cranes in the side slope sites has the advantages of speedy mounting and high efficiency.

Description

technical field [0001] The invention belongs to the field of crane installation, and in particular relates to an installation method of crawler cranes in slope sites. Background technique [0002] Crawler cranes are bulky and inconvenient to move. Generally, the parts of the crane are transported to the site and then assembled. The assembly steps are as follows: first level the site, then assemble the main engine, crawler belt and counterweight, and finally assemble the boom. Because the boom is long and heavy, generally speaking, when assembling the boom, it is necessary to assemble and connect the boom on a flat ground before hoisting it to the main engine. However, in the actual construction process, if you encounter a slope site, especially a site with a relatively large height drop, it is difficult to find a suitable flat site to assemble the boom. Contents of the invention [0003] For above-mentioned deficiencies in the prior art, the technical problem to be solve...
